摘要:
Climate is universal. If a major modern nuclear war (i.e., with a large number of small‐yield weapons) were to happen, it is not even necessary to have a specific part of the world directly involved for there to be cause to worry about the consequences for its inhabitants and their future. Indeed, smoke from fires ignited by the nuclear explosions would be transported by winds all over the world, causing dark and cold. According to the first study, by Turco et al. [1983], air surface temperature over continental areas of the northern mid‐latitudes (assumed to be the nuclear war theatre) would fall to winter levels even in summer (hence the term “nuclear winter”) and induce drastic climatic conditions for several months at least. The devastating effects of a nuclear war would thus last much longer than was assumed initially. Discussing to what extent these estimations of long‐term impacts on climate are reliable is the purpose of thi

摘要:
The cover of the March 11, 1986, issue of Eos featured an attractive color world map entitled “Relief of the Surface of the Earth,” published jointly by several agencies. It is stated that the Mercator projection is used, as indeed it appears and is so labeled. In fact, this is not a true Mercator. The detail on the map, as available to the public, deviates from its correct position by as much as 3.2 mm (53 km) at 65°N and S latitude given the printed scale of 1:39,000,000 for the equator. This will not be a problem for many applications of the map, but it can seriously affect attempts to overlay other data o

摘要:
The conversion of a set of early Landsat data from wide band videotape to digitized, computer‐compatible form is slated to end prematurely when this fiscal year ends on September 30, 1986. The National Aeronautics and Space Administration (NASA) is shutting down the project to save money because of the Gramm‐Rudman‐Hollings deficit reduction act (Eos, January 28, 1986, p. 41) and in view of the strain on NASA's budget caused by the loss of the space shuttle Challenger, according to Joseph Bishop, program manager for data processing in NASA's Office of Space Tracking and Data Systems. Moreover, the only equipment that can be used to read the wide band videotape data and convert it to computer‐compatible tape (CCT) has become obsolete, and the tapes themselves are deteriorating, so it seems unlikely that this project could be renewed in the future, according to Allen H. Watkins, chief of the Earth Resources Observation System (EROS) Data Center of the U.S. Geological Survey in Sioux Falls,

摘要:
The Continental Scientific Drilling Program at Valles Caldera, N. Mex., enters its second phase in August as drilling begins at Sulphur Springs, an area of acid‐sulfate springs and mudpots on the western flank of the caldera's resurgent dome. The hole will be available for scientific study for 3 to 5 year

摘要:
For the tectonic, structural, or surficial geologist, a geologic map is the ultimate document, encompassing within its bounds a concise display of the current status of geologic information for the region that it embraces. Because the state of Maine, areally, is half of the New England region, the new bedrock and surficial maps of that state, produced under the direction of State Geologist Walter Anderson with the collaboration of 13 bedrock area compilers, 12 surficial areal compilers, and aided by funding from the U.S. Department of Energy and the Maine Geological Survey, are important contributions to our knowledge of this portion of the northern Appalachian Mountains. These maps follow closely upon recently published bedrock maps of Massachusetts (E.‐A. Zen et al., U.S. Geological Survey, Washington, D.C., 1983) and Connecticut U. Rodgers, Connecticut Geological and Natural History Survey, Hartford, 1985). Revisions of maps for the other New England states are in progres
